      I was 13 years old.  My family had moved to Southern California from North Florida a year before. 

 I hit adolescence with a vengeance.  I was angry and rebellious, with little regard for anything my parents

had to say, particularly if it had to do with me.  Like so many teenagers, I struggled to escape from

anything that didn't agree with my picture of the world. A "brilliant without need of guidance" kid, I

rejected any overt offering of love.  In fact, I got angry at the mention of the word love.

     One night, after a particularly difficult day, I _____________, shut the door and got into bed.  As I

lay down in the privacy of my bed, my hands slipped under my pillow.  There was an envelope.  I pulled

it out and on the envelope it said, "To read when you're alone."

     Since I was alone, no one would know whether I read it or not, so I opened it.  It said "Mike, I know

life is hard right now, I know you are frustrated and I know we don't do everything right.  I also know

that I love you completely and nothing you do or say will ever change that.  I am here for you if you ever

need to talk, and if you don't, that's okay.  Just know that no matter where you go or what you do in your

life, I will always love you and be proud that you are my son.  I'm here for you and I love you - that will

never change.  Love, Mom.

That was the first of several "To read when you're alone" letters.  They were never mentioned until I was

an adult.

Today I travel the world helping people.  I was in Sarasota, Florida, teaching a seminar when, at the end

of the day, a lady came up to me and shared the difficulty she was having with her son.  We walked out

to the beach, and I told her of my mom's undying love and about the "To read when you're alone" letters.  Several weeks later, I got a card that said she had written her first letter and left it for her son.

     That night as I went to bed, I put my hands under my pillow and remembered the relief I felt every

time I got a letter.  In the midst of my turbulent teen years, the letters were the calm assurance that I

could be loved in spite of me, not because of me.  Just before I fell asleep I thanked God that my mom

knew what I, an angry teenager, needed.  Today when the seas of life get stormy, I know that just under

my pillow there is that calm assurance that love - consistent, abiding, unconditional love - changes lives.
